Stretford Plants

Economical Cleanup of Hydrogen Sulfide

For applications in which the produced hydrocarbon or hydrocarbon product has a relatively low sulfur content, PPE offers an effective, low cost method to remove the sulfur compounds from hydrocarbons. The process uses reduction-oxidation (redox) chemistry to oxidize hydrogen sulfide into elemental sulfur using an alkaline solution containing vanadium as an oxygen carrier.

PPE has designed and built hydrogen sulfide removal plants based on the Stretford Process that are operating successfully today.
